The emergence of the earlier pioneers of pediatric psychiatry was associated with the evolution of understanding of child psychiatric disorders. Pediatric psychiatry begins with the recognition that children are not simply small adults. Through the insights of figures such as Thomas Willis, Henry Maudsley, and Hermann Emminghaus, the field gradually gained recognition and understanding. Important milestones include the work of William Thierry Preyer and Alfred Binet in developmental psychology, which laid the groundwork for pediatric psychiatry. Bibliometrics, a method for analyzing academic publications and citations, offers insights into the impact and influence of scholarly work and its authors. Increasingly, bibliometric assessments are being employed to evaluate the scientific productivity of academic leaders in various medical disciplines. This book present a study focuses on utilizing bibliometrics, particularly the H-index calculated via Google Scholar Citation analysis, to identify academic leaders in clinical pediatric psychiatry.
